    Sport Performance Sound. Mustang owners love the power and performance their GT's possess, especially when dropping it into a lower gear to pass slow moving traffic, but they find the sound of the stock exhaust a little anemic. So give your GT the exhaust note it deserves by upgrading to a Corsa Performance Sport Cat-Back Exhaust System. Acoustically engineered and tuned, this Corsa Sport Cat-Back will give your V8 coyote powered Mustang a robust, sport performance sound under acceleration and a distinct rumble at idle, all without any annoying drone while cruising. As an added bonus a Corsa Sport Cat-Back will also improve your Mustang's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

    Race Car Growl. Corsa Performance Sport Cat-Back Systems feature a very unique double helix X-Pipe that replaces the factory resonator Mid Pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.

    RSC™ Technology. Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC™). RSC™ Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

    Quality Construction. Corsa Performance proudly manufactures their Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3 inch diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-Pipe and two high flow, straight-through sport mufflers. The mufflers feature a pair of mirror polished twin 4 inch Pro-Series tips. Step down flanges are included, so that this 3 inch Corsa Cat-Back can be installed with the factory 2.5 inch exhaust.

    Application. This Corsa Sport Cat-Back Exhaust System with Polished Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018-2019 Fastback GT Mustangs that is not equipped with the Active Valve Exhaust System.

    Application Note. The 2015-2017 Model Years will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.

      Corsa sport 3 inch cat back exhaust system

      I used to have the corsa extreme on my 2015 5.0 mustang and it was great but alittle bit to loud,, so on my new 2018 5.0 mustang I went with the corsa sport and I am glad I did because it's perfect,,still has that great corsa sound but its toned down just enough to keep the neighbors happy, I highly recommend the corsa sport exhaust

      Corsa Sport

      Owns up to the promise of absolutely no drone. Made of the best materials and had good fitment. Took less than an hr to install. My only regret was I should have paid a little extra for the black exaust tips to match the black wheels on my performance pack.

      Great exhaust

      Huge improvement over the stock exhaust! I like how its not super loud at idle, but it roars once you get on it.

      Sport vs extreme debate

      I bought the sport cat back due to not wanting to anger the neighbors. I immediately felt I made the wrong choice and feared the sport was not going to be loud enough or have an acceptable tone like I wanted from watching the videos on the extreme. (And also my wife said she didn’t want the loudest system and asked me to not order the extreme). Called corsa, and found the sport is 15 dB over stock at WOT and the extreme is 24 dB over stock at WOT. INSTALL REVIEW... put it up on the lift and initially had it all done in 45 minutes. My tail pipes were hitting the rear bumper cutouts like many have stated. I dropped the hangars and adjusted both rear muffler hangars to better center the tips and it now looks perfectly centered. But will not look this good without adjustment manually. Just bent them inboard to get desire clearance fit. With all the fine tuning with fitment issues, it took 1 hour and 45 minutes which included a 10 minute shake down drive followed by the hangar bending. SOUND REVIEW... I was so sure it was not going to be loud enough and was certain I made a mistake by not buying the extreme... She sounds perfect. Exceeded expections of acceleration noise. I actually don’t think it needs to be any louder. I searched high and low to find a review where someone was looking at both options and got the sport and was saying If they wished they got the extreme. Here is that answer. I do not feel I made a mistake. I do not regret not getting the extreme. I honesty think the sport catback is louder than what YouTube videos show. I am very happy with the end result. And I’m the guy that is all for nascar loud pipes on the road.

      Corsa Sport cat-back

      Most companies claim direct fit bolt on. Had to do some modification to the rear hangers to make them hang evenly. Decent sound but wanted something more aggressive and should have went with the Corsa Xtreme.
